The world in AD 1750
TL;DR — In 1750 Bach died in Leipzig, rival chiefs held Isfahan for a Safavid figurehead, Korea cut its military cloth tax, and Spain agreed to give seven Guarani missions to Portugal.
Three years after the murder of Nader Shah in June 1747, the lands he had ruled were still being divided among tribal chiefs, and a new Afghan kingdom at Qandahar was taking the eastern half. In the Deccan a French column of 800 Europeans and 3,000 sepoys helped put a new viceroy over the Deccan, which counted six of the Mughal empire’s 22 provinces. Spain and Portugal redrew their border in South America on paper, and in Seoul King Yeongjo pushed through a tax cut his court had debated since the 1650s. Leipzig lost its cantor of St. Thomas, Johann Sebastian Bach, on July 28.
Africa
At the Cape of Good Hope, the Dutch East India Company colony depended on enslaved labor brought across the Indian Ocean. South African History Online records that India supplied about 80 percent of the Cape’s slaves in the early 18th century, that a slaving post at Delagoa Bay was opened in 1721 and given up in 1731, and that between 1731 and 1765 more and more slaves were bought from Madagascar. The same account puts the Cape’s slave population at 2,500 in 1720 and 14,500 in 1790.
West Asia
Isfahan, the old Safavid capital, changed hands in 1750 in the name of a dynasty that no longer ruled. Encyclopaedia Iranica records that Karim Khan, chief of the Zand, and the Bakhtiari chiefs Ali-Mardan Khan and Abu’l-Fath Khan occupied the city that year for a Safavid princeling, Abu Turab, whom they styled Shah Ismail III. Ali-Mardan then killed his partner and raided Shiraz, and Karim Khan came back to Isfahan in January 1751, defeated him, and took the title of wakil, or regent. Iranica dates his rule over Persia outside Khorasan from 1751 to 1779.
Europe
Johann Sebastian Bach spent the last months of his life nearly blind. The chronology kept by the Bach-Archiv Leipzig records that his health failed in 1749, with a serious eye condition and trouble in his right arm and writing hand, and that the ophthalmologist John Taylor, in Leipzig from April 4 to 7, 1750, operated on him; complications required a second operation. Bach regained some sight for a short time, then had a stroke and died on July 28, 1750. He had finished the Mass in B minor two years earlier.
East Asia
King Yeongjo of Joseon made the year’s largest fiscal change in Korea. According to the National Institute of Korean History, a survey of commoner men and the cloth they owed for military service was completed in 1748, and it showed that cutting the levy from two bolts of cloth per man to one would leave the treasury about 500,000 bolts short. Senior ministers objected, but with the backing of the minister of war Hong Gye-hui the king ordered that from 1750 each man pay one bolt, and he set up an office to find other revenue. The reform was proclaimed as the Equal Service Law (gyunyeokbeop) in September 1751.
South Asia
A French column marched out of Gingee on December 4, 1750, and by the next morning the Deccan had a new viceroy. The British historian Robert Orme recorded that Nasir Jang, subahdar of the Deccan, was killed in his own camp by one of the Pathan nabobs allied with him, and that his nephew Muzaffar Jang, a prisoner in fetters for seven months, was hailed as ruler of a province that Orme estimated at more than 35 million people. Orme wrote that apart from the conquests of Cortés and Pizarro, “never did so small a force decide the fate of so large a sovereignty.” At Pondicherry that evening Joseph-François Dupleix held a court to receive congratulations, and a Te Deum was sung the next day.
Central Asia
Nader Shah’s assassination on June 9, 1747, left the oasis khanates in the hands of their own chiefs. Encyclopaedia Iranica records that in Bukhara the Manghit leader Muhammad Rahim Ataliq had put the khan Abu’l-Fayz to death and then ordered the killing of his young son and successor, Abd al-Mu’min, at a date Iranica places between 1750 and 1751. In Khiva the Manghits lost power in 1752, and in the Ferghana valley the Ming rulers held Kokand, founded in 1740. South of the Amu Darya, Ahmad Shah Durrani, crowned near Qandahar in October 1747, had made Nader’s grandson Shahrukh his vassal in Khorasan in 1749 and annexed Bactria and Badakhshan in 1751.
The Americas
Seven Jesuit missions and some 30,000 Guarani stood on land that the Treaty of Madrid of 1750 gave to Portugal. The Harvard historian Tamar Herzog writes that the Spanish king promised to evacuate them, that the Guarani could take their movable goods, and that the houses, churches and lands would pass intact to Portugal. Guarani leaders wrote letters of protest and from 1753 tried to coordinate a response; most refused to leave, and the war that Spain and Portugal fought against them from 1754 to 1756 left most of the missions destroyed or abandoned. The treaty was annulled in 1761.
Oceania
Trepang, the sea cucumber prized as a delicacy in China, brought boats from Makassar in Sulawesi to the north coast of Australia. In a 2010 review in PLoS One, Kathleen Schwerdtner Máñez and Sebastian Ferse cite historians who date these voyages from at least 1750 until South Australia banned them in 1906 and 1907; the fishing grounds were Marege, now Arnhem Land, and Kayu Jawa, on the Kimberley coast. Makassar’s registered exports of trepang rose from 71 tons in 1733–34 to 301 tons in 1766–67. The first European report of the fleets in Australia came from the British hydrographer Alexander Dalrymple in 1768.
